board: stm32: Add Engicam i.Core STM32MP1 C.TOUCH 2.0

Engicam C.TOUCH 2.0 is an EDIMM compliant general purpose Carrier
board.

Genaral features:
- Ethernet 10/100
- Wifi/BT
- USB Type A/OTG
- Audio Out
- CAN
- LVDS panel connector

i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.

i.Core STM32MP1 needs to mount on top of this Carrier board for
creating complete i.Core STM32MP1 C.TOUCH 2.0 board.

Linux dts commit details:

commit <6ca2898df59f> ("ARM: dts: stm32: Add Engicam i.Core STM32MP1
C.TOUCH 2.0")

Add support for it.
